BRACKET.

SPECIFICATION forming' part of Letters Patent No. 594,862, dated December 7, 1897.

Application filed January 30, 1897. Serial No. 621,283. (No model.)

To all whom it may concern:

Be it known that I, CHARLES F. DOEBLER, a citizen of the United States, residing in Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Brackets, of which the following is a specifica-tion.

This invention relates to brackets; and it has for its main object the provision of an improved wall-bracket formed of sheet metal in such a manner as to combine extreme lightness with very great strength,.all of the parts of which bracket are simplein construction and may be stamped out and put together at a low cost.

In the drawings accompanying and forming part of this specification, Figure-1 is a plan of my improved bracket. Fig. 2 is a side elevation of the saine. Fig. 3 is a front elevation of the same. Fig. 4 is a diagonal section taken in line a ct, Fig. 2, looking in the direction of the arrow and illustrating the manner of connecting the ribs, which constitute the main feature of the inventiomwith the sole and the wall-plate of the bracket. Fig. 5 is a detail side elevation of a sheet-metal Wall-bracket, illustrating a modification of my invention; and Fig. 6- is a detail sectionalv viewillustrating the connection with the main rib of the bracket, of a modied form of auxiliary rib, which will be referred to more particularly hereinafter.

Similar characters designate like parts in all the figures of the drawings.

My improved wall-bracket will, as before stated, be constructed entirely of sheet metal, except as to the rivets or other suitable means for holding the members together, and it comprises as its essential features va sole and a wall-plate connected in any suitable manner and preferably made in one piece, a main rib connecting the sole and the wall-plate, and an auxiliary rib disposed transversely to the main rib and connecting the latter with the main members of the bracket at the point of intersection of the sole and the wall-plate.

rIhe improved bracket that constitutes the subject-matter of my present invention is designated in a general Way by B. The sole and the wall-plate thereof, which are desigat right angles to each other and are preferably formed from a single flat strip of sheet metal bent at the point 2 to form an L-shaped piece that constitutes the main member of the bracket.

In the construction illustrated in the drawings the sole and the wall-plate also have rectangular perforations 2", 3", and 5, which form rivet-holes adapted -to receive the heads of suitable rivets projecting from oppositeends of the main rib of the bracket and from the' upper end of the auxiliary rib.

The main rib of the wall-bracket is designated by 4 and will also be of sheet metal and preferably curved, so as to receive the strain to the best advantage and transmit the same to the auxiliary rib, While taking up a small amount of space and permitting the parts to be organized compactly. It will be noted that this Vmain rib is disposed edgewise to the sole and the wall-plate, so as to forni a stiff brace, and that the rib also has at its opposite ends rivets that enter the corresponding perforations 2" and 3l in the sole and the Wall-plate, respectively, and are headed up to retain the rib in its proper position.

The auxiliary rib, which, in connection with the main rib 4, constitutes the principal feature of this invention, is disposed transversely to the main rib and preferably in such a position asto lie in the diagonal line bisecting the angle formed at the junction of the sole and the wall-plate. This auxiliary rib is designated in a general way by 5' and will also be formed of sheet metal, as are the other members of the bracket. l

In the construction shown in Figs. 2, 3, and 4 this auxiliary rib is formed from a strip of metal bent a-t its central portion to form an eye or loop 5', adapted to receive the main rib 4, while the free ends of the auxiliary rib are brought together and beveled off and shaped so as to form projecting rivets 57, adapted to enter the corresponding rivet-holes 5 adjacent tothe point of intersection of the sole and the Wall-plate and to be headed up to retain said auxiliary rib in its proper position.

It will be seen by reference to Fig. 4 that the auxiliary rib shown therein and in Figs. 2 and 3 is of double thickness, and hence exceedingly stiff. In order properly to cony nect the main rib and the auxiliary rib, so as IOO to prevent movement of these members relatively to each other, I prefer to form registering-perforations in the main rib and in the opposite sides of the loop 5 and pass therethrough a rivet 6, which will be headed up in the usual manner.

Although the form of device illustrated in Figs. 2 to 4, inclusive, is preferred by me, it will be apparent that the construction and organization of the main and auxiliary ribs are capable of slight modification Without departing from my invention.

In Fig. 5 the main rib a and the auxiliary rib 5 are made in one piece in any suitable manner-for instance, by stamping from a single piece of sheet metal; but in this construction, as in that illustrated in Fig. 2, the main rib is curved inwardly, and the auxiliary rib is disposed transversely to the main rib andconnected with the main portion of the bracket at the point of intersection of the sole a-nd the Wall-plate.

In Fig. 6 I have shown a detail illustrating an auxiliary rib in which a loop 5c is formed u substantially similar to that illustrated at 5',

Fig. 4, except that the blank forming the auxiliary rib in Fig. 6 is just long enough to form the loop 5 and does not continue on to the point of intersection of the sole and the Wall-plate to form a rib of double thickness, as is the case in Fig. 4.

The usual screw-holes 7 will be stamped in the sole and in the Wallplate at suitable points for the purpose of securing the bracket to a Wall or other part.

I-Iaving described my invention, I claim- 1. A bracket comprising a sole and a Wallplate connected and having rivet-holes; a lnain rib disposed edgewise to the sole and the Wall-plate and having at its ends integral longitudinally-extending rivets adapted to enter the proper rivet-holes in said members; and an auxiliary rib projecting from the main rib, substantially at the central point thereof,

and also disposed edgewise to the sole and the Wall-plate and having at its end an integral longitudinally-extending rivet adapted to enter a rivet-hole adjacent to the point of intersection of the main members of the bracket.

2. A sheet-metal bracket comprising a sole and a wall-plate connected and having rivetholes one of which is located at the point of intersection thereof; a main rib disposed edgewise to the sole and the Wall-plate and having at its ends integral longitudinally-extending rivets adapted to enter the proper rivet-holes in said members; and an auxiliary rib projecting from the main rib, substantially at the central point thereof, and also disposed edgewise to the sole and the Wallplate and having at one end a loop encircling the main rib and riveted thereto and having at its opposite end an integral longitudinallyextending rivet adapted to enter the rivethole at the point of intersection of the main members of the bracket.

3. A sheet-metal bracket comprising an integral sole and Wall-plate having rivet-holes one of which is located at the point of intersection thereof; a main rib disposed edgewise to the sole and the wall-plate and having at its ends integral longitudinallyextending rivets adapted to enter the proper rivet-holes in said members; and an auxiliary sheetmetal rib of double thickness' also disposed edgewise to the sole and Wall-plate and having a loop at one end riveted to the main rib, substantially at the central point of the latter, and having at its other end an integral longitudinally-extending divided rivet adapted to enter the rivet-hole at the point of intersection of the main members of the bracket.
